"Ammoco" was one of the high performance fuels of the sixties. My parents
used only Ammoco in both their 55 Buick Century and (my favorite) my dads
1957 TR-3. I used it in my "souped-up" lawn mower. We had no one problem
what so ever with any engine. In 1963 the Buick became mine, did a
compression (over 100,000 mile) found one bent valve, problem with the
fuel--NO. The valves and seats were so good that they did not require a
grind or a reseat.
If I remember correctly, Ammoco Supreme was 102 octane. If they could do it
then why can't we have 100 octane now??
